Virtual slide telepathology systems with JPEG2000.

In this paper the JPEG2000 standard is analyzed showing how to exploit all its powerful features in order to build efficient virtual slide telepathology systems. We propose a fast method for stitching images in the wavelet domain. Stitching is a process necessary in many virtual slide systems to generate only one image of a slide with the maximum resolution. This method profits from the structure of the JPEG2000 images to carry out the process with the minimum memory consumption and computational load, obtaining a smoothed union without losing any detail.
